A new modeling approach shows that the ocean circulation determines the varying rate of global temperature response to carbon dioxide.

Novel modeling experiments show that heating near North Africa leads to drying near North America.

A rocket will thunder off from a NASA launch pad this weekend, carrying a handful of seeds that are part of a science experiment in which PNNL plays a key role.

Researchers find surface evaporation drives circulation and summer precipitation in the Tropical West Pacific.

Hurricanes that intensify rapidly do so more strongly and quickly now than they did 30 years ago.

Improving the representation of upper-ocean layers in hurricane forecast models enhances their predictive skill.

Over 100 scientists and engineers from multiple DOE national laboratories and universities, including PNNL, contribute to the creation of a new Earth modeling system—the Energy Exascale Earth System Model.
